[. . . ] MPEG Portable Analyzer AD954 Features & Benefits Supports MPEG-2/DVB/ATSC Transport Streams Which Enables Testing to be Performed Anywhere in the World Real Time Monitoring of Key Parameters Gives an Immediate Indication of Major Problems Detailed Off Line Transport Stream Analysis Enables Full In-depth Analysis of the Transport Stream Transport Stream Capture and Triggered Recording Provides the Capability to Send Streams Back to Base ASI, SMPTE 310M, DVB Parallel Interfaces for Connection Anywhere in an MPEG-2 Network Small, Light and Portable Low Power Consumption Overview Applications Installation and Commissioning of DVB/ATSC Transmission Chains Testing and Debug of MPEG-2 Broadcast Equipment The AD954 is a small, portable unit with enough power to debug MPEG-2 systems in the field. [. . . ] This gives "live" stream compliance status and highlights errant stream behavior. DVB Testing AD954 provides real time monitoring of all the DVB defined first priority measurements*1. It also gives status of the transport error indicator and detects unreferenced PIDs A real time view of the SI tables is provided ATSC Testing In addition to the basic transport stream tests a real time view of the PSIP table is provided PID Bit Rate Testing User selected PIDs may be tested to check whether their bit rate remains constant for a period of greater than 1 second. The multiplex occupancy is tested against user definable limits on either a per PID or per program basis. Installation engineers can thereby confirm that statistical multiplexers are functioning correctly 2 MPEG Test · www. tektronix. com/video_audio MPEG Portable Analyzer AD954 Characteristics Product Specifications DVB Real Time Analysis SI Table checks*2 MPEG-2 measurements as defined above PID bit rate measurement Ordering Information AD954 Platform Network Interfaces ­ AD954 is compatible with a Pentium class laptop or higher running either Windows 95 or Windows NT operating systems. To ensure optimum performance of real time monitoring we recommend that a PC with a performance equivalent to a Pentium 300 MHz unit running Windows 95/98 with 64 MB RAM or running Windows NT with 128 MB RAM is used with AD954.
